If you see “couldn’t connect to 1Password” in your browser

Get help when you can’t use 1Password in your browser because the extension can’t connect to the app.

About the message

1Password 6.8 for Mac introduced a more reliable method for saving and filling in browsers called native messaging.

Native messaging improves the performance and reliability of the 1Password extension, especially when proxies, antivirus, and other security software would otherwise interfere with 1Password. If 1Password is unable to detect support for native messaging in your browser, you’ll see this message.

What you should do

For all browsers

First, try restarting your browser. If you’re still having trouble, follow these steps to allow 1Password to use native messaging in your browser:

Open Terminal, which is in the Utilities folder of your Applications folder.

Copy and paste the following command and press Return:

mkdir -p ~/Library/Application\ Support/Google/Chrome

Open 1Password and click the 1Password menu. Hold down the Control and Option keys on your keyboard. While holding the Control and Option keys, select “Quit 1Password and 1Password mini”.

Open 1Password again.

Restart your browser.

Follow the additional steps below if you use Brave, Vivaldi, or Chrome Canary.

If you use Brave

If you use Brave, make sure you’re using Brave 0.17.19 or later. Earlier versions do not have support for native messaging.
